Blackboard bold: Verskil tussen weergawes

In [[Unicode]], a few of the more common blackboard bold characters ('''C''', '''H''', '''N''', '''P''', '''Q''', '''R''' and '''Z''') are encoded in the [[Mapping of Unicode characters#Basic Multilingual Plane|Basic Multilingual Plane (BMP)]] in the ''Letterlike Symbols (2100–214F)'' area, named DOUBLE-STRUCK CAPITAL C etc. The rest, however, are encoded outside the BMP, from <code>U+1D538</code> to <code>U+1D550</code> (uppercase, excluding those encoded in the BMP), <code>U+1D552</code> to <code>U+1D56B</code> (lowercase) and <code>U+1D7D8</code> to <code>U+1D7E1</code> (digits). Being outside the BMP, these are relatively new and not widely supported.

 

The following table shows some of the more common uses of blackboard bold.

 

A blackboard bold Greek letter mu (not found in Unicode) is sometimes used by number theorists and algebraic geometers (with a subscript ''n'') to designate the group (or more specifically [[group scheme]]) of ''n''-th roots of unity. A blackboard bold numeral 1 is often used in [[set theory]] for the [[top element]] of a forcing poset.
